COVER FOR GAS-GLOBES.

SPECIFICATION forming part of Letters Patent No. 245,714, dated August16, 1881.

Application filed May 6, 1881. (No model.)

To all whom it may concern:

Be it known that I, JAooB GRUENEBAUM, of the city, county, and State ofNew York, have invented certain new and useful Iin provements in (loversfor Gas-Globes, of which the following is a specification.

This invention has reference to an improved cover or cap for gas-globes,by which a more perfect combustion of the carbon particles in the gas isobtained, separate smoke-bells dispensed with, and the blackening of theceiling and walls by the deposit of carbon entirely obviated.

The invention consists of a smoke cap or cover for gas-globes, which isconstructed with a central depression at its top and an annular bulgearound its sides, and provided with an outwardly anddownwardlyprojecting baserim adapted to fit loosely over the top rim ofthe globe, and with slots or openings arranged above the rim for theescape of the gases of combustion. This central depression tends todirect the currents outward, and, together with the symmetricalspherical bulge, tends to produce an upward central current andcircumferential downward currents free from choking eddies, causing auniform mingling of the gas and atmospheric air, thereby promoting asteady and complete combustion.

The accompanying drawingrepresents a side view of my improved cover forgas-globes, in which A represents asmoke cover or cap,which ispreferably made of opaque glass, and of any suitable size and design.This cover is constructed with a central depression at its top, and witha symmetrical annular bulge, the upper side of which forms a continuouscurve with line of said depression. The cover A is fitted by means ofabottom rim, a, to the top edge of the glass globe with which it is to beused, and is provided above the rim with a series of slots or openings,b, of circular, elongated, or other shape, which are arranged in thelower part of the cover, the arched top part being closed and providedwith a central exterior button or handle device, d, which serves to takehold of the cover in placing it in position on the globe or removing ittherefrom. When the cover is placed upon the globe the particles ofcarbon which heretofore have escaped unburned, so as to be depositedupon the smoke-bells or the ceilingand walls, are thoroughly burned atthe inside of the globe, the gases of combustion being emitted throughthe slots 11 of the cover.

The smoke-cover can be used with any gasglobe of corresponding size, isreadily removed for cleaning, produces a better and steadier light, andforms an ornamental attachment to the gas-globes. In show-windows it hasthe additional advantage of protecting the goods exhibited thereinagainst the danger of being burned.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- A cover for gas-globes constructed with a closed tophaving: a central depression, and with a symmetrical annular bulge theupper side of which forms a continuous curve with the line of saiddepression, said cover being provided with an outwardly and downwardlyprojecting recessed lip adapted to fit closely over the top of theglobe, and with holes around its lower parts above said lip,substantially as described.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of two witnesses,this 29th day of April, 1881.

JACOB GRUENEBAUM.
